What is the best way to create buy in from the students regarding classroom rules and consequences?

The following dialogue occurs between Mr. Jimenez and a parent while discussing the benchmark data at a parent-teacher conference.

Mr. Jimenez: Thanks for coming, Ms. Lester. Cameron told me that he scored three goals at his soccer game last night.
Ms. Lester: Yes, I am very proud of him. Did Cameron take the state standardized reading test already?
Mr. Jimenez: No, it was a test created by the district.
Ms. Lester: How do these tests help him?
Mr. Jimenez: Teachers analyze the data from these tests, along with other information gathered about students, to plan appropriate instruction. I think this is a good time to discuss Cameron's reading skills by looking at this test and other information I have collected. Cameron reads very fluently and with great expression. He really shines when we perform readers' theater. Based on the test results, it looks like we need to focus on improving his skills in reading comprehension and higher-order thinking. (Mr. Jimenez and Ms. Lester continue to discuss Cameron's reading skills.)
Mr. Jimenez: Do you have any additional questions or concerns?
Ms. Lester: I looked into getting a tutor to help Cameron with reading, but he did not want to go by himself. Can you give me a list of other students who could use extra help with reading?

The most appropriate response from Mr. Jimenez to Ms. Lester's final question about tutoring is for him to make which of the following statements?
